There are many attitudes towards and ways of approaching the issue of IT security. Which of these are the most useful and effective depend on the situation and priorities of the company concerned - and how far you have come in your efforts to establish and maintain the desired degree of security. It is important to invest in precisely the security measures that provide optimum protection in relation to the needs of your company. As security can be difficult to finitely measure, we have developed a simple method to describe security levels - and thereby ease the task of identifying the security requirements of your company:   How secure do you wish your IT systems to be? We have drawn up a security model that illustrates how a company can work with IT security of a technical nature. The majority of companies prioritise one or more of the areas at a time in the security model - rather than tackling all the areas simultaneously.
